Jake Posted March 7, 2004 Share Posted March 7, 2004 What would be involved in a V8 conversion for a Supra? Has anyone in the UK done it before? Any opinions on what would be the best choice of engine? I'm presuming an aluminum block US engine. Would it be best to mate the V8 to the Supra auto box using some sort of adapter or use the gearbox that goes with the new engine? Would there be a lot of electrical problems? Would the ECU still be required for something? Quote Link to comment Share on other sites More sharing options...

SkyJawa Posted March 7, 2004 Share Posted March 7, 2004 My guess would be to use the 4.0l V8 out of the Soarer if you want to do it ??!?!?! Being from the same manufacturer........ Quote Link to comment Share on other sites More sharing options...

dude Posted March 7, 2004 Share Posted March 7, 2004 Use a small block chevy stroker engine , roller cam the alloy heads and Holley Projection also use the TH7R4 gearbox , 5-600 reliable HP is easily obtainable with no lag and monstrous Torque , this is on my list of to do's as soon as a cheap blown up N/A shows up !!!!

Matt Harwood Posted March 7, 2004 Share Posted March 7, 2004 If you were to do it, I'd go for a good old fashion Chevy lump You wouldn't need the ecu for anything if you went with the box too. I think Dude was thinking of this some time ago. Quote Link to comment Share on other sites More sharing options...

This: http://www.megaboost.co.uk/supra/photos/lexusv8insupra.jpg Looks nice and full Has anyone in the UK done it before? I've never seen it done here, it's not a very British thing to do I guess. Any opinions on what would be the best choice of engine? I'm presuming an aluminum block US engine. How about keeping it in the family with a 3UZFE? Don't the current batch of Supra JGTC cars use that or another Toyota V8? Not as cheap as a US engine no doubt and probably not as much tuning stuff out there (maybe?) but it'll look nicer Would it be best to mate the V8 to the Supra auto box using some sort of adapter or use the gearbox that goes with the new engine? Using a Lexus lump might make it easier? Would there be a lot of electrical problems? Would the ECU still be required for something? Does the Supra have seperate ECUs for things like the PAS and ABS etc? I guess anything is possible.... Quote Link to comment Share on other sites More sharing options...

Pfft - tiny for us in the real world, but for those in third world areas down south who still think a 1400baud modem is fast there may be problems. I dont care mate, I thought it was funny. Seen emins motor for sale ? OOps slight thread-hijack there, back to V8's (puuurrrrrr) I am guessing that a supreme amount of cash injection would be called for and at that sort of rate you may be better off looking to buy a car with a V8 already in and tune it. I would imagine you could better spend your money elsewhere for a similar power-hike out of the V6?!? Quote Link to comment Share on other sites More sharing options...
Syed Shah Posted March 7, 2004 Share Posted March 7, 2004 I6 now V6! Why bother, the 2jz can but out just as much power as most V8s. What to you hope to achieve? Quote Link to comment Share on other sites More sharing options...

Jake Posted March 7, 2004 Author Share Posted March 7, 2004 I see we're expriencing the traditional mkivsupra.net Thread Drift, thanks StealthHosts. Why would I want to do a V8 conversion? Well what else could you replace the TT lump with? As Dude says, you can massive power and torque from a V8. It should be reliable and simple, no turbos to blow up, no injectors or ECU to worry about. And it would sound fantastic too! I'm not saying that I'm definitely going to do it, I'm just exploring the feasibility really. I've read about the GT Supras racing in Japan that use a Lexus 3UZ-FE 4.3 litre V8 bored out to 5.2. I'm guessing that you could do it a lot more easily and more reliably with US parts though. Quote Link to comment Share on other sites More sharing options...

It should be reliable and simple, no turbos to blow up, no injectors or ECU to worry about. And it would sound fantastic too! I wasn't questioning your idea, just putting the point across that there is more than one way to skin a cat, going on the costs involved (I have no idea how much in total but I am guessing a lot) there may be other more time/cost effective solutions for you.

I'm guessing that you could do it a lot more easily and more reliably with US parts though. One thing I would say..... it'd be a beast and a half!!!!! If you do decide to do it then good luck, it would be an amazing sight to see (and hear for that matter). Even if you don't decide to do it then keep this updated with stuff you find out, I'm sure a great many people would be interested in seeing it done.

dude Posted March 7, 2004 Share Posted March 7, 2004 Try PAW or JEGS for a crate engine and Projection kit , then you need ancillaries and would want alloy heads for the weight saving , to my mind the ideal candidate for this would be a N/A Aerotop !!!

Excuse my ignorace but what's a Projection Kit? Why would you want an N/A over a TT as a base car? Just because they're cheaper to buy? Either way I certainly don't want a Aerotop Quote Link to comment Share on other sites More sharing options...

Either way I certainly don't want a Aerotop Holley Projection !!, its a very basic injection set up using a 4 barrel manifold and very easy to set up and map via a handcontroller and its cheap as well , why start with a TT worth say £10K when you can start with an N/A worth £5K and end up with it owing the same as the TT before you start Your right an Aero is far to good for you , stick with the hardtops !!!!

MONKEYmark Posted March 8, 2004 Share Posted March 8, 2004 that lad i normally talk to at york and elvington drag strips has a mad car all home made stuff. 4l v8 with twin turbos, 100% metonol injection, a huge 300 shot of nos and 4wd cortina. he was telling me he has/is buying a big block chevy from a drag anglia it has run 7 second 1/4`s in the anglia its an 11 liter engine. he was going to put 2 t78`s on it and nos it up. sounds like a crazy idea. there is another guy at york has built a caterum type car with a v8 engine, he got engine out of scrap yard. he runs mid 10`s the supra with a v8 sounds good. also wasnt there supposed to be a big block chevy supra going to that top speed event?
